BACKGROUND

1. Technical field

The embodiments herein generally relate to a security system and particularly relate to the security system for artificial water bodies such as swimming pools. The embodiments herein more particularly relates to a swimming pool cover assembly and a movable board positioned over at any elevation inside swimming pool to prevent drowning of users.

2. Description of the Related Art

Often children die in the swimming pools because of either not being familiar with swimming or other factors such as falling suddenly in the swimming pool filled completely with water or empty pools. Further the swimming pools need to be changed to safe areas in which no child dies due to playfulness and no adult dies due to lack of knowledge of swimming or falling in pools. Also there is no opportunity to save the person quickly, even if a person is injured because of dropping into the swimming pools

Numerous swimming pool covers have been devised for covering the swimming pools during periods when they are not in use, to keep out children and animals that might fall in and get drowned, to keep out dust, dirt and leaves during the unused periods and to preserve the cleanliness of the pool. These pool covers are of the types such that they are usually positioned over the pool, attached to the anchors, secured in places by laces, or provided with a continuous tube filled with water attached to the cover along its border and holding the cover slackly in place. However these covers are heavy, difficult to adjust, difficult to handle, take a long time to fill and a long time to empty.

Hence there is a need for a security system provided with a movable cover having an adjustable mechanism to move the cover to different depths to provide water pool of desired depths in accordance with a plurality of requirements. There also exists a security system provided with a movable reticular board which encloses the water body to prevent debris, dust, etc., from accumulating in the pool. Moreover, there exists a need for a security system provided with a movable reticular board which is adapted to convert the pool into a multi-utility area when the pool is not in use.

The abovementioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.

With respect to FIG. 1, the security system includes a water body 102 with a plurality of jacks 106 installed to control the direction of movement of a reticular structure 104. The reticular structure 104 is a rectangular board provided with the flexibility required to align with the shape of the water body. The reticular structure 104 as shown in FIG. 1 is aligned with the bottom of the water body. The particular height at which the reticular structure 104 is placed is predetermined by a user. The reticular structure is made of composites and lattices which are joined by joints. The force determined for each square meter is 3000 N/m². The force is calculated by a security factor of 3 and also the water pressure.

FIG. 2 illustrates a perspective view of a security system with a reticular structure arranged at a desired height in a water body, according to one embodiment herein, while FIG. 3 illustrates a perspective view of a security system with a reticular structure arranged at a water level on the top of the water body, according to an embodiment herein. With respect to FIG. 2 and FIG. 3, the security system includes the reticular structure 104 with a plurality of jacks 106 installed to control the direction of movement of the reticular structure 104. The reticular structure 104 is moved vertically in a direction along the depth/height of the water body 102 to a desired height according to the requirements of the user. The particular height at which the reticular structure 104 is placed is predetermined by a user. The user adjusts the height of the reticular structure 104 by pressing a button in a remote controller. The pressing operation by the user results in transferring a command to a central controlling unit. The central controlling unit receives the command and sends a control command to the plurality of hydraulic components to a desired height of the reticular structure 104 according to the requirements. The reticular structure 104 includes physical characteristics to permit the flow of water across the reticular structure 104 resulting in the movement towards the highest point in the water body as shown in FIG. 2. The reticular structure 104 is moved towards the top of the water body 102 by sending commands through the remote controller such that the reticular structure 104 covers the open surface area of the water body 102 when the water body 102 is not in use as shown in FIG. 3.

FIG. 4 illustrates a block circuit diagram of an electro hydraulic circuit in the security system, according to an embodiment herein. The electro hydraulic circuit includes a plurality of hydraulic components. The plurality of hydraulic components includes at least one hydraulic pump 402, an electromotor 404, at least one discharge divider 406, at least one hydraulic jack, at least one direction control valve 408, a plurality of pressure relief valves, a control balance valve, and at least one counter balance valve. The hydraulic pump 402 is connected to the electromotor 404 and provides the discharge needed by the four hydraulic jacks. The discharge is divided equally by the discharge dividers 406 into four for equalizing the velocity of the hydraulic jacks. Further the direction of the jacks is controlled by the direction control valves 408. The electro hydraulic circuit is simulated by automation studio software.

The hydraulic pumps 402 require a driving force to provide the needed torque of the circuit. This torque should be supplied by the electromotor 404. Further all the hydraulic pumps 402 used in high pressure hydraulics are positive displacement pumps. The ability to provide high pressure without reducing the output rate is the main characteristic of the hydraulic pumps 402. The hydraulic pumps 402 used in the present system include a gear pump and a piston pump. The gear pump includes two gears which are meshed with each other and are sealed in a close case. Further as the axle that is connected to one of the gears rotates, the suction occurs on one side, and discharge occurs on the other side. The piston pump includes an oblique plate that is connected to the end of a piston axle. Further a full round rotation of the oblique plate changes the position of the piston from suction to discharge.

The security system also includes a controlling system for controlling the revolution of the electromotor 404. The revolution of the electro motor 404 is controlled through frequency inverters. The frequency converters are used when there is a need to achieve the maximum revolution of the electric motors. Further as the electromotor 404 starts working a sudden movement of the pump may strike the jack and by using revolution control inverters, the motor revolution is accelerated with a pacific slope. The changing frequency and voltage is the basis of inverters function in a way that voltage or frequency ratio is kept constant. Further the motor torque is constant in different motor revolutions.

The discharge dividers 406 are precise hydraulic motors and have gears' rotational speed equal to each others. Further when the fluid enters the hydraulic motors, the motors function in contrary to gear pumps. The rotation of one or more tandems which are in mesh with each other and also the connection of their spinning axis to each other leads to a passage of equal amount of discharge through each tandems. Further due to the tolerance between the gears and the cover, an amount of liquid leaks and as the speed of the gears increases, the discharge will be divided more precisely.

A circuit undesirably gets closed and consequently a part of the circuit gets ruptured because of high pressure. Further when the pressure exceeds limits during such an event it is necessary to use a plurality of pressure relief valves to create a path underpass. The plurality of pressure relief valves releases the pressure created due to the hydraulic movements in the water body. The pressure of relief valves is adjustable and their size depends on the circuit discharge.

The security system includes one or more direction control valves 408 to control the direction of movement of the plurality of jacks 106. The number of ports and the valves position is determined depending on the function of the security system. The size of the direction control valves 408 depends on the maximum discharge passing through the valves.

The security system also includes a plurality of counter balance valves. The plurality of counter balance valves are used to control the velocity of the plurality of the jacks 106 and are used in the direction of the load. The counter balance valves also obstruct the drain path to achieve the desired pressure required in the system.

The electro hydraulic circuit also includes an input and output equipment. The input and the output equipment include control switches that are connected to the output ports of the Programmable logic controllers (PLC). PLC is simple computer systems used in industrial environments and work with logic controlling algorithms. Further microprocessors used in PLC are simpler than PCs. The microprocessors in PLC receive the inputs through sensors by loading the program. After processing, the commands are sent to the operators through the output ports. The new PLCs rea e also capable of sending and receiving the DC analog signals. The security system also includes an emergency power supply system that has been contrived to provide energy of the system in emergency situations such as power outage or any other unexpected event. The emergency power supply system is a kind of a hybrid generator that works with gas or gas oil. Further when the fuel tank is in full charge mode, the generators continuously provide the power to run the security system.

FIG. 5 illustrates a pictorial representation of a transmitter in the remote controller of the security system, according to an embodiment of the present disclosure while FIG. 6 illustrates a pictorial representation of a receiver in the remote controller of the security system, according to an embodiment herein. With respect to FIG. 5 and FIG. 6, the remote controller includes a transmitter 502 and a receiver 602. The user operates the security system installed in the water body 102 by pressing a button in the transmitter of the remote controller. Further by pressing the buttons on the transmitter, the user transmits certain commands to the receiver as shown in FIG. 5.

The receiver 602 receives the radio waves from the transmitter 502 and transmits the commands to a relay through an encoder. The user then turns back the reticular structure in the security system to an earlier position by pressing a button which in turn avoids the drowning of the user in the water body 102. The remote controller is worn by the user on the wrist before entering the water body 102.

FIG. 7 is a schematic diagram illustrating a management system to control the range of motion of the jacks, according to an embodiment herein. The security system includes a central controlling unit 702. The central controlling unit 702 is capable of confining the range of motion of the plurality of jacks 106. The central controlling unit 702 confines access to various stages through three on/off switches. The various stages include a first stage 702, a second stage 704, and a third stage 706. The particular height at which the reticular structure 104 is placed is predetermined by the user. The user presses a button on the remote controller and the remote controller transfers a command to the central controlling unit. The central controlling unit 702 sends a control to the plurality of hydraulic components to adjust a particular height of the reticular structure 104 according to the requirements. Further the water flows through the reticular structure 104 resulting in the movement towards the highest point in the water body 102.

FIG. 8 is a pictorial representation of a telescopic jack in the security system, according to an embodiment of the present disclosure. The plurality of jacks used in the security system is a telescopic jack 802. The telescopic jack 802 in the security system is selected based on the jack load calculated. The calculations are listed below:

The dimensions of the floor in addition to live load is given by the below expression:

24 (m²)×150 (Kg/m²)=3600 (Kg).

F=36000 (N).

Further assuming that the applied load on each jack equals to the force applied and the expression is given below:

360000 (N)÷4=9000 (N).

Therefore four prince jacks model are chosen for the security system.

The maximum input discharge to each jack is 50 LPM (restriction is because of output discharge of the cylinder as the jack is negative). The force of jack has been calculated based on plunger. Thereby the applied force by a jack in maximum pressure is given by the below expression:

F ₁ =P×A=200 E+5 (Pa)×2.28 E−3 (m²)=45600 N.

Further during this situation the allowed course of the jack equals to 2.13 m and the applied force by a jack in minimum pressure is given by the below expression:

F ₂ =P×A=70 E+5 (Pa)×2.28 E−3 (m²)=15960 N.

Further from the above expression, the allowed course of the jack equals to 3.98 m and the jack force will prevail over the load. Thus the telescopic jack is selected in the security system.

FIG. 9 illustrates a perspective view of an electro hydraulic circuit in the security system, according to an embodiment herein. With respect to FIG. 9, the electro hydraulic circuit 902 includes a control feedback system 904 for controlling and equalizing the velocity of jacks. Further there are many changes in electro hydraulic circuit in the first plan as shown in FIG. 4. The electric valves are replaced with servo type valves and a plurality of analog sensors is used with the plurality of jacks. Further more complicated controlling algorithms are used in the electro hydraulic circuit.

FIG. 10 illustrates a perspective view of a PLC input-output circuit in the security system, according to an embodiment herein. With respect to FIG. 10, a PLC input-output circuit 1002 includes four pressing buttons functioning as input and few of the buttons work manually and others are controlled from distance by radio waves. Further two of the switches are contrived to control the movements in reciprocating movement and also to control the construction from two separate locations.

FIG. 11 illustrates a perspective view of a ladder diagram on which rational control algorithms are applied, according to one embodiment of the present disclosure. With respect to FIG. 11, the ladder diagram 1102 displays a kind of program that is conducted in PLC processors. Further in this program the position of input command switches are checked and then the commands are transferred to one of the coils of direction control valves.

The various advantages of the present disclosure are to provide a security system with a reticular structure arranged on a ground level in a water body for safety of the users. Further the security system prevents drowning of the users in the water body by adjusting the height of the reticular structure according to the requirements. The reticular structure covers the open surface area of the water body when the water body is not in use which in turn prevents the user falling inside the water body. The construction of the reticular structure with the plurality of jacks in the water body is flexible and is cost effective. The user is also provided an option to determine a level that the user wants to swim and change the level accordingly. The security system is also helpful to provide hydrotherapy for elderly and disabled people and also children.
